Yepp we just blew are lower unit and bought one like 2 weeks ago. 3 year unconditional warranty, they are best if you are running a 200 or below. I have a 225, and I am going to have to buy bobs nose cone. Other than that you cant beat it for that price.
they manufacture there own housing, all the internal parts are omc, no fault 3 year warranty( even if you run it with no oil) they have done years of R&D they have a test lake on site, looking at the factory housing vs SEI you can really see no difference, i think the inside of the SEI is cleaner less burs. Hard to beat
